Okay thanks 97SL320, I was finally able to see a low speed RPM drop at about 1200..slight shift in sound as I manually grounded the negative side. And thank god for fuse seven which saves the works when you hit the wrong pins and ground the feed. So I should be able to observe continuity to ground when the rpm hits the 2000 range and the ECU closes the ground path..The advance mechanism could be fine but Im still thinking about its appearance of being bent a little, bent attachment bolt perhaps. The actuation was free and the advance system seemed to work fine. And now it also occurs that the reason for lower performance feel and MPG could be the result of having ASR on this car which my other did not..And that wagon suspension and added weight.
